The purpose of this study was to assess the sagittal cephalometric characteristics of young adult Lebanese individuals and assess gender-related differences.
Conventional lateral cephalograms were obtained from 117 subjects. Eight linear/angular measurements combining sagittal parameters selected form McNamara and Steiner analyses were recorded. Paired t-test was applied to evaluate differences between genders and skeletal classes.
Males showed significantly greater maxillary and mandibular length than females. ANB was larger in females with no significant differences in SNA values indicating that Lebanese females tend to have a more convex profile than their male counterparts. Subjects with skeletal Class III tended to have a retrognathic maxilla rather than a prognathic mandible.
Sexual dimorphism is evident in young Lebanese adults relative to linear skeletal dimensions regardless of the skeletal class. Skeletal determinants of Class III malocclusions may be different from those of other population groups.
本研究旨在评估黎巴嫩年轻成年人的矢状面头颅测量特征,并评估性别差异。
从117名受试者获取传统的侧位头颅X线片。记录了从麦克纳马拉分析法和施泰纳分析法中选取的8项结合矢状面参数的线性/角度测量值。采用配对t检验评估性别和骨骼类型之间的差异。
男性的上颌骨和下颌骨长度显著大于女性。女性的ANB角更大,SNA值无显著差异,表明黎巴嫩女性的侧貌比男性更凸。骨骼III类受试者倾向于上颌后缩而非下颌前突。
无论骨骼类型如何,黎巴嫩年轻成年人在骨骼线性尺寸方面存在明显的性别差异。III类错牙合畸形的骨骼决定因素可能与其他人群不同。
